UK Construction Industry Statistics: Data, Trends and Outlook

UK construction output grew by 0.3% in the second quarter of 2026, new orders fell by 11.8% over the same period, and 370,770 registered construction firms were operating across Great Britain at the last count. Those three numbers sum up the sector fairly well: activity is holding, the forward pipeline is thinning, and an enormous number of small businesses are competing for what remains.

This page pulls together the construction industry statistics that matter for businesses operating in the UK and Ireland, sourced to the original publications and dated so you can see how current each figure is. It covers output, company numbers, workforce demand, insolvencies, regional performance across Northern Ireland and the Republic of Ireland, and the digital adoption data that most industry reports skip.

Construction Industry Statistics: The Current Data Snapshot

Construction contributes roughly 6% of UK gross domestic product and remains one of the largest employers in the economy. The short-term picture is one of flat volume rather than decline, with growth concentrated in infrastructure and repair work rather than new building.

Two figures in that table deserve to be read together. New work output reached a record £140,684 million in 2024, driven entirely by public sector spending, which rose 6.7% while private sector work fell 0.7%. New orders then dropped sharply in the second quarter of 2026. Output is a record of work already done; orders are a signal of work to come. When one is at a high and the other is falling, the sector is working through a backlog rather than building a pipeline.

Where the construction data actually comes from

A lot of published construction industry data is recycled from secondary aggregators without attribution, which is how five-year-old figures end up presented as current. If you are building a business case or a tender submission, go to the primary sources. The Office for National Statistics construction industry section publishes monthly output bulletins and an annual statistics release covering firm numbers, employment and output by type of work. CITB publishes the Construction Workforce Outlook for skills and labour demand. The Insolvency Service publishes monthly company insolvency statistics with industry breakdowns. NISRA covers Northern Ireland separately through its Quarterly Construction Enquiry, and the Central Statistics Office covers the Republic of Ireland.

Between them these sources cover output, employment, firm numbers, construction market data by region and sub-sector, and the main construction industry trends worth tracking. Each is free, updated on a published schedule, and specific enough to answer most questions a contractor or consultancy will have. There is no single construction industry database that brings them together, which is why so much of the commentary you see online is thin.

How Many Construction Companies Are in the UK?

There were 370,770 VAT and PAYE registered construction firms operating across Great Britain in the third quarter of 2024, a 1.7% increase on the same period in 2023, according to ONS data drawn from the Inter-Departmental Business Register. That figure covers Standard Industrial Classification Section F: construction of buildings, civil engineering, and specialised construction activities such as electrical work, plastering and demolition.

That total is the answer to two of the most common questions asked about the sector: how many construction companies operate in the UK, and how many builders there are in the UK. The honest answer to the second is that nobody knows precisely, because the number of construction companies in the UK captured by official registers is a floor rather than a ceiling.

It is worth knowing what the number does not include. The IDBR counts registered enterprises, so businesses below the VAT threshold and many sole traders sit outside it. The register also classifies firms by their main economic activity and by their registered address, which means a contractor headquartered in Belfast but working across the water is counted once, in Northern Ireland.

The practical meaning of 370,770 firms is competitive density. In most trades and most postcodes, a prospective client has dozens of credible options. That is the context for everything else on this page, and it is why the businesses that win consistently tend to be the ones that are easy to find and easy to verify. A firm with a clear website built around its project portfolio is doing something that most of its 370,769 competitors have not bothered to do properly.

Construction Workforce Statistics: Employment, Skills and the Recruitment Gap

The UK construction sector employed 2,606,380 people in 2025 and needs an average of 41,200 additional workers every year between 2026 and 2030 to meet forecast demand. That is roughly 206,000 extra people over five years, equivalent to 1.6% of the 2025 workforce, according to the CITB Construction Workforce Outlook published in June 2026.

Note that the 2026 to 2030 requirement is materially lower than CITB’s previous outlook, which put the annual figure at 47,000 to 2029. The gap narrowed because the output forecast softened, not because recruitment improved. CITB expects output to fall 0.2% in 2026 before returning to growth of 1.8% in 2027 and 2.8% in 2028, with infrastructure, public new housing and private new housing as the main growth sectors.

Which trades are hardest to recruit

The SME State of Trade Survey, run jointly by the Federation of Master Builders and the Chartered Institute of Building, is the only regular survey focused specifically on small and medium-sized construction firms. Its findings for the second half of 2025 put carpenters at the top of the difficulty list, cited by 30% of firms, followed by bricklayers at 29% and plumbing and HVAC roles at 23%.

The more interesting finding sits underneath those trade categories. In the first half of 2025, 64% of firms reported difficulty finding workers who understand the building safety regime, and 59% could not find staff with sustainable building and new technology skills. The construction skills shortage is no longer only about people who can lay brick. It is increasingly about people who can operate the compliance, digital and low-carbon side of a modern project.

That distinction matters for how firms respond. Recruiting a bricklayer is a labour market problem. Building compliance and digital capability inside an existing team is a training problem, and one that structured digital training for staff can address without waiting for the labour market to loosen. CITB levy-registered employers should check current eligibility under the CITB grants scheme and Skills and Training Fund before paying for short courses out of general overhead.

Recruitment is also a visibility problem. A candidate weighing two local employers will look both of them up, and the firm whose website was last touched in 2019 loses that comparison before anyone reads a job description. This is the part of marketing for construction companies that gets least attention: it works on the hiring side as hard as it works on the sales side.

Mental health in the construction workforce

Any honest account of construction workforce statistics has to include this. ONS figures record 355 deaths by suicide among people working in skilled construction and building trades in 2024, among the highest counts of any occupational group. Research published by the Chartered Institute of Building in 2025 found roughly a quarter of surveyed workers had experienced suicidal thoughts in the previous year.

The Lighthouse Charity, which supports construction workers and their families, reported a 25% rise in families contacting it during the first quarter of 2026 compared with the same period a year earlier, alongside a 44% increase in counselling sessions delivered. The charity has pointed to self-employed and finishing trades as the group most exposed, sitting at the end of the payment chain where budgets and timelines are tightest.

The Lighthouse Charity runs free and confidential 24/7 helplines on 0345 605 1956 in the UK and 1800 939 122 in the Republic of Ireland.

Regional Construction Data: Northern Ireland, Ireland and the UK Nations

National construction industry statistics flatten out very large regional differences. Northern Ireland and the Republic of Ireland are both running well ahead of the Great Britain average, and any contractor planning on the basis of UK-wide figures alone will misread their own market.

Northern Ireland construction output was 23% above its pre-pandemic level in the first quarter of 2026, with housing at a 15-year high. Output dipped 1.0% over the quarter after three consecutive quarters of growth, but the annual figure of 10.1% tells the more useful story: while Great Britain output has been broadly flat, Northern Ireland has been growing at pace.

The Republic of Ireland picture is stronger still on housing. Completions reached 36,284 in 2025, the highest annual total since the series began in 2011 and 20.4% up on 2024, with apartment building up 38.7%. The first quarter of 2026 delivered 7,856 completions, a 32.9% rise on the same quarter of 2025 and the highest first-quarter total on record. Around 195,600 people were employed in Irish construction in the first quarter of 2026, with 62% working mainly on new housing or renovation. Average hourly labour costs in the sector reached €33.39, up from €32.11 a year earlier.

One caution on the Irish data. Completions fell 16.4% year on year in the Dublin region in the second quarter of 2026 while the Border region grew 14.6%. Growth is real but it is moving around the country, and a firm that planned its year on Dublin apartment volume has had a different 2026 to one working in Cavan or Donegal.

For firms bidding across both jurisdictions, this divergence is a content opportunity as much as an operational one. Publishing genuinely local material about the conditions in your service area is one of the more reliable ways to build search visibility for a construction business, because almost nobody in the sector does it.

Construction Insolvency Statistics: The Financial Pressure Behind the Output Figures

Construction recorded 3,841 company insolvencies in England and Wales in the 12 months to June 2026, the highest of any industry and 17% of all cases where an industry was captured, according to Insolvency Service company insolvency statistics.

Set that against a second published figure and it becomes more informative. Construction accounted for around 14% of all registered businesses in the UK as of September 2025 but 17% of insolvencies. The sector fails at a rate above its share of the business population, and it has done so consistently.

The trend is easing rather than worsening. The rolling 12-month total to May 2026 was 6% below the equivalent figure a year earlier, though still around 18% above the pre-pandemic 2019 level. Firms classified under specialised construction activities, largely subcontractors doing groundwork, electrical, plumbing and finishing work, consistently make up the largest share.

The distribution is the point. Main contractors dominate the headlines when they collapse, but the failures are concentrated among subcontractors sitting furthest down the payment chain. For an SME in that position, the practical defences are commercial rather than digital: staged payment terms, retention tracking, and enough client diversity that one bad debt does not take the business down. The digital contribution is narrower but real, which is that a steady flow of inbound enquiry reduces dependence on any single main contractor relationship.

Digital Adoption in Construction: BIM, AI and the Data That Nobody Collects

The most-cited digital construction figures in the UK come from the NBS Digital Construction Report, whose 2025 edition found that close to 88% of respondents were using or planning to use Building Information Modelling, that around half of architecture professionals had adopted AI tools, and that eight in ten used cloud computing to collaborate on models and documents, up 11 percentage points in two years.

Those numbers are accurate and they are also frequently misused. The NBS sample is drawn from more than 550 built environment professionals, weighted towards architects, designers, engineers and BIM specialists. It is not a sample of the 370,770 registered construction firms, and it is certainly not a sample of the two-person roofing contractor or the eight-person groundworks firm. When a trade publication reports that “88% of UK construction has adopted BIM”, it is reporting a finding about design professionals and applying it to an industry that is overwhelmingly made up of very small subcontractors.

The gap is wider than BIM. There is no reliable construction marketing data for the sector either: no published series tracking website quality, enquiry sources or marketing spend among small contractors, in the way that financial data for construction businesses is tracked through Companies House filings and insolvency records. The commercial side of the industry is simply not measured.

The honest position is that nobody publishes reliable digital adoption data for SME construction firms in the UK and Ireland. There is no equivalent of the ONS output series for website quality, CRM usage or digital marketing spend among small contractors. That absence is itself one of the more useful construction industry statistics available, because it means the competitive gap in this area is unmeasured and, for most firms, unexploited.

What can be said with confidence is where the technology is genuinely landing. Digital takeoff and AI-assisted estimating are the first meaningful adoption point for most small contractors, well before anything involving drones or digital twins, because they attack the single most expensive unbilled activity in a small firm: pricing work that it does not win. ProfileTree’s guide to AI in construction covers that ground.

As Ciaran Connolly, founder of ProfileTree, puts it: “Construction companies are often brilliant at their trade but invisible online. A contractor doing outstanding work in Belfast or Derry can lose a tender to a competitor with a weaker portfolio simply because their website hasn’t been updated in five years.”

Sustainability Statistics and the Future Homes Standard Deadline

The Future Homes and Buildings Standards were published on 24 March 2026 through the Building Regulations etc. (Amendment) (England) Regulations 2026, alongside new Approved Documents L and F. The regulations come into force on 24 March 2027, with certain provisions applying to higher-risk building work from 24 September 2027, subject to transitional arrangements.

That is a firm date, and it applies to England only. New dwellings built to the standard are intended to require no retrofit work to reach zero carbon in use once the electricity grid is decarbonised, which in practice means high fabric efficiency and low-carbon heating rather than gas boilers. Northern Ireland, Scotland and Wales set their own building regulations on separate timetables.

For contractors, the commercial reading is straightforward. There are roughly twelve months of transitional runway, and the firms that spend it building demonstrable competence in low-carbon construction and retrofit will be positioned differently to those that wait. The FMB and CIOB finding that 59% of SME firms cannot recruit staff with sustainable building skills tells you how thin the supply of that competence currently is.

Demonstrating the capability is a separate exercise from having it. A retrofit specialist with no published material describing its work will lose enquiries to a firm that has documented a handful of projects properly. ProfileTree’s overview of green construction and sustainable building covers the territory in more depth.

What the Statistics Mean for SME Construction Businesses

Pull the figures together and a consistent picture emerges for small and medium-sized firms. There is work, particularly in infrastructure, repair and maintenance, and housing in Northern Ireland and the Republic of Ireland. There is severe competition, with 370,770 registered firms in Great Britain alone. There is financial fragility concentrated among subcontractors. And there is a skills gap that is shifting from trade skills towards compliance, sustainability and digital capability.

Four practical responses follow from that, each grounded in something the data actually shows.

Treat your website as procurement infrastructure. Public construction contracts across the UK and Ireland are advertised through Find a Tender, Contracts Finder and eSourcing NI, and buyers routinely check a bidder’s website before shortlisting. A site that cannot demonstrate relevant completed projects, accreditations and capacity is doing active damage during that check. This is not a design question; it is whether the evidence a procurement officer needs is present and findable. This construction software website design project shows what a properly structured technical portfolio looks like.

Build search visibility for the work you actually want. A groundworks contractor in Belfast and a commercial fit-out firm in Cork are competing in entirely different search markets, both of which are far less contested than national terms. Search engine optimisation for a construction firm is largely a matter of being specific about trade, location and project type, which most competitors are not.

Film the work, because construction photographs well and almost nobody does it. Time-lapse capture during a build, site walkthroughs, and handover documentation all produce material usable on a website, in a tender submission where supporting media is permitted, and in recruitment. Video production and marketing is one of the few areas where the sector’s visual nature is a genuine advantage that goes largely unused.

Publish what you know. A civil engineering consultancy that writes a clear explanation of public sector procurement processes, or a retrofit contractor that documents a Future Homes Standard-ready specification, establishes credibility before any sales conversation begins. This is also, in practice, how a firm’s own construction data and project experience gets turned into something that generates enquiries. Building that capability in-house is often more sustainable than outsourcing it, a trade-off covered in this piece on why businesses need digital training.

The Outlook to 2030

CITB forecasts average annual output growth of 1.8% across 2026 to 2030, with a soft 2026 giving way to recovery from 2027 and growth peaking mid-period. Infrastructure, public new housing and private new housing carry most of that growth. The Republic of Ireland is targeting 300,000 homes between 2025 and the end of 2030, and Northern Ireland’s housing output is already at a 15-year high.

The pressures do not resolve on the same timeline. The workforce gap of 41,200 people a year persists across the whole forecast period. Insolvency remains around 18% above pre-pandemic levels even as it eases. The Future Homes Standard lands in March 2027 with compliance costs attached. Construction industry statistics over the next five years will most likely describe a sector that is growing modestly while restructuring underneath, with the firms that invest in skills, compliance and visibility separating from those that do not.

ProfileTree works with construction, property and trade businesses across Northern Ireland, Ireland and the UK on web design, SEO, content marketing, video production, digital training and AI implementation. If your firm’s online presence does not reflect the standard of the work, that is a fixable problem.
